Patented in Germany August 8, 1888, No. 46,796 in France August 3, 1888,170. 192,209; in Sweden August 8, 1888, No. 1,717; in Norway August 4, 1888,110. 1,012 inItaly September 80, 1888, XXII, 28,926, XLVII, 218, and in Austria-Hungary December 20, 1888, No. 86,098 and No. 55,722.

To all whom it may concern.-

Be it known that I, RUDoLF REITHOFFER, a subject of the Emperor of Ausaria-Hungary, residing at Rudolfsheim, near Vienna, in the Province of Lower Austria, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Egg-Boilers, (for which I have obtained Letters Patent in the following countries: in Austria- Hungary, dated December 20, 1888, No. 36,093 and No. 55,722; in Germany, dated August 3, 1888, No. $6,796; in France, dated August 3, 1888, No. 192,209; in Italy, dated September 30, 1888, Reg. Gen. Vol. XXII, No. 23,926, Reg. Att. Vol. XLVII, No. 218; in Sweden, dated August 3, 1888, No. 1,717, and in Norway, dated August 4, 1888, No. 1,012 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap-' pertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Referring to the drawings, Figure 1 is a seetional elevation of my improved egg-boiler, showing the parts in their operative position. Fig. 2 is a like view showing the parts in their relative position after the boiler has completed its downward motion, the boilercover, the egg-carrier supports, the time mechanism and its support, and other parts being omitted. Fig. 3 is a rear elevation of the clock-casing, showing the releasing and. alarm mechanisms and devices.

The invention relates to egg-boilers, and has for its object to provide means whereby the eggs are automatically removed from the boiler after having remained in the boiling water for a predetermined time.

To these ends the invention consists in the combination, with a fixed egg-carrier, of a movable boiler and a heating device for said boiler; in the combination, with the movable boiler and heating device, of an extinguisher for automatically extinguishing the heaterfiame; in the combination, with the boiler, of a time mechanism, a locking device for look ing the boiler against movement, and a reneeted to a short sleeve, 0

leasing mechanism controlled by the time mechanism to release the boiler, and in certain structural features and combinations of elements, substantially as hereinafter described, and as set forth in the claims.

In the drawings, A indicates a base-plate or support, to which are secured three standards, B B and If. The standard 7L3 carries the time mechanism, hereinafter to be described, and the standards B B carry the egg-carrier. The standards B are preferably hollow, so that the egg-carrier may be removably connected therewith.

The egg-carrier consists, first, of a support-= ing-yoke, C, comprising the arms 0 0 the outer or free end of which is bent to form a loop or eye, 0 while the inner ends are con- Headed pins 0, passing through the eyes 0 and into the standards B, serve to connect the yoke with the standards, thus providing a stationary support for the egg-carrier.

The egg-carrier proper consists of a tube, cl, that has secured thereto a plurality of egg rings or loops, D, or is provided with a disk suitably perforated for the reception of the eggs, and said tube is supported at its lower end by the short sleeve 0 of the yoke O. In the upper end of the tube (Z is seated a handle, G, to which a cover is secured that has a suitably-slotted flange to fit over the arms 0 of the yoke O to close the boiler E when in its operative position, as shown in Fig. 1.

WVithin the tube d is fitted a second tube, c, that has a spiral slot, 0 formed therein the whole length thereof, said slotted tube projecting slightly below the short sleeve c", with which it is rigidly connected. In the slotted tube 0' is fitted a spindle, e, that is provided with a pin, 6, projecting into the slot 0 of tube 0, and the lower end of said spindle c is rigidly secured to the bottom of the boiler E, which is preferably a cylindrical vessel of sheet metal. The upper and lower terminals of the slot 0 limit the vertical move ment of the boiler and its spindle within the tube 0.

As shown at E, a portion of the bottom of the boiler is made to project and has its edges made flaring, such portion acting as a deflector for the flame of a lamp, F, so as to more uniformly distribute the heat over the boiler-bottom, to which is also secured an extinguisher-cup, e ,tl1at fits over the wick-tube of the lamp.

The lamp F is preferably supplied with alcohol, and may have 'a cylindrical or flat wick tulr e, f The fount itself may also be of cylindrical and preferably of slightly tapering form, and is supported in an elevated position by means of a spiral spring, f, arranged in a sectional telescopic casing or housing, F composed, as shown, of two sections, f f

It will be observed that v by providing a spiral slot and imparting a compound rotary vertical motion to the boiler the locking device for the latter need not be as strong as it would have to be when the boilerhas a simple rectilinear motion, for the reason that the full weight of the boiler does not bear upon such locking device. In fact, but a very slight resistance to the motion of the boiler will hold it in position, so that no powerful mechanical device need be employed to release said boiler. I am thus enabled to employ a time mechanism of a compact form .and simple in construction, which I will now describe. The time mechanism comprises a power-spring and a main arbor, 72. which carries or which may be revolved by a windingkey, h, to wind up the power-spring, said arbor carrying also a hand, 7L7.

In combination with the spring and arbor I employ a minute-train of gearing controlled by an escapement and a pendulum, h, which train of gearing, escapement, and powerspring I have deemed unnecessary to show, as such are well known, though I would remark that the hand-arbor a is revolved by the spring and minute-gear in a direction the reverse of that in which it revolves when winding up the spring, so that the hand 71 will always indicate the time to which the mechanism isset and when the winding up is to be stopped. For instance, as shown in Fig. 1, the arbor it has been rotated to wind up the springuntil the hand reached the threeminute indicator. The winding up having then ceased, the boiler will be released, when the hand returns to 0, the time mechanism being limited to ten minutes in the example given, which is more than ample for boiling eggs to any desired degree.

The devices for locking the boiler against motion and for automatically releasing the same consist of a radial arm, 6 secured to the boiler, and a stop arm, h, pivoted to the back frame-plate of the clock mechanism and projecting through the clock-casing H into the path of the radial arm 6 which, when the boiler is in its most elevated position, bears against said stop-arm h, as shown. It further consists of a disk, h secured to the main arbor 71/, said disk being provided with a lifter-pin,

* 7L2, in the path of the stop-arm h, which lifts the latter out of the way of the radial arm a On said disk h is also pivoted a pawl, h that operates a-tripping-arm on the bell-hammer pivot to lift the hammer H against the stress of its spring h and strike the bell B, thus sounding an alarm simultaneously with the release of the boiler, h being the abutment-pin for the pawl to hold it in position.

The operation of my improved boiler is as follows: The parts being in their relative positions, (shown in Fig. 1,) the clock is wound up to bring the hand to the three-minute indicationthat is to say, the arbor h has been rotated from right to left, or. in the direction of the arrow, until the hand starting from zero or 10 reaches the index 3, and then stopped. The boiler will now remain in the position shown for nearly three minutes, when, the releasing devices being in about the position shown in Fig. 3, a further movement of disk 7?. will lift the arm h out of contact with the arm e and the pawl It will trip the hammer to sound the alarm, while the hand M will have traveled backward to zero. The boiler under its own weight will now revolve and descend, the extinguishencup will extinguish the flame of the lamp F, which under the weight of the boiler will be forced into the housing F, and said housing will be telescoped. Inasmuch as the egg-carrier is stationary, the eggs will be automatically removed from the boiling water, as shown in Fig. 2. The cover G during the downward motion of the boiler will also remain in its position, being supported by the carrier-tube d and the carrier-yoke C. The radial arm a also serves as a handle to move the boiler into the position shown in Fig. 1.

The advantages of my improved egg-boiler will be readily understood.

Having described my invention, what I claim is r 1. An egg-boiler composed, essentially, of

socketed supports, an egg-carrier provided with arms terminating in an eye, and locking-pins adapted to pass through said eye and fitting into the sockets of the supports, in combination with a boiler adapted to move in the plane of the carrier, said carrier being constructed to fit into said boiler, substantially as and for the purposes specified.

2. In an egg-boiler, the combination, with a revoluble boiler havinga simultaneous vertical and rotary motion on its support and a stationary egg-carrier constructed to fit into said boiler, of a locking device to lock said boiler against rotation and vertical motion, substantially as and for the purposes specified.

3. In an egg-boiler, the combination, with arevoluble and vertically-movable boiler pro vided with a radial stop-arm and a stationary egg-carrier constructed to fit into and arranged in the plane of motion of said boiler, of a locking-lever adapted to engage the stop arm of the boiler, and a timed releasing mech anism to break the engagement between the arm and lever, substantially as and for the purposes specified.

4. In an egg-boiler, the combination, with a movable boiler and a stationary egg-carrier constructed to fit Within said boiler, of means for imparting a vertical and rotary motion to said boiler, consisting of a stationary helically-slotted tube and a support for the boiler fitting into said tube, said support being provided with a radial pin extending into the helical slot of said tube, substantially as and for the purposes specified.

5. The combination, with the stationary egg-carrier, consisting of the supporting-yoke C, sleeve 0 thereof, carrier-tube d, and carrier D, connected therewith, and the spirallyslotted tube 0', of the boiler E, and the spindle e, secured to the bottom of the boiler and projecting axially therethrough and through the tube 0, and the guide-pin e, secured to RUDOLF REITHOFFER.
